Letters Patent No. 104,212, dated June 14, 1870.

GRATE AND FIRE-POT FOR HEATING-STOVES.

The Schedule referred to in these Letters Patent and making paxt of thesame.

I, PHILIP JACOB ScHorr, ofLousville, in the' county of J eiiersou, Stateof Kentucky, have invented a certain Improvement' in Heating-Stoves, ofwhich the following is a specification.

The first part' of lmy invention relates to the better support andeasier movement of grates placed in Stoves. lhe second part of myinvention relates to the combination, with tbegrate, of `a perforatedconical or cylimhical-shaped receptacle or fire-pot, for c oal used asfuel.

rlhe third part of my invention relates4 to thc combination of aperforated conical 'or cylindrical-shaped tube with the grate.

The object of my improvements is First, to effect a better support ofthe grate, and

at the same time an easier movement, unobstructed. by particles of fuelfallingthrough the bars of the grate. s

Second, to isolate the burning fuel, to some extent, from the outer wallof the stove, and prevent that wall becoming over-heated and red hot bycirculation of ail between it and the fire-pot containing the burningfuel.

rlhird, to admit abundance of atmospheric air to alll regulated bydampcrs on the outer wall of the stove.

Fourth, to prevent the escape'of the poisonous carbonic-oxide gasthrough the side' walls of iron stoves into the room.

By the experiments of MM. Deville and Traost, French chemists, andGeneral Morin, of the French Academy ofScicnce, the permeability of ironheated to a high degree, by gases, has been proved conclusively.

rlheformation of this dangerous gas is caused by imperfect combustionand the want of oxygen contained in atmospheric air.

By my invention abundant air, already heat-ed by coming in contact withradiating iron, is conducted to the burning coal, and, by isolatingthetire-place from the outer wall, and causing a free circulation aroundit, the obnoxious gas, even when formed, will be carried off through theventilating pipe before penetrating through thc'side wallsof the stove.

With a litt-le care the draught can be so regulated by dampers as toprevent the outer wall of the stove from getting red hot, and allow theescape of the gas.

Description of the'Accoiiipmiying Drau/'tulp v'Figure 1 is a plan of theinvention.

is a vertical transverse section ou line General Description.

A is the base of a stove, with four brackets, B, act` ing as a 'supportto the lire-pot C.

.lo reduce'friction, these brackets arerounded on their upper surface;they are provided with a guard, b, also rounded. 4

`Ou these brackets -rests the i'e-potlU, perforated with numerous smallholes, round or square, and provided around the entire circle with adepending flange, a, fitting to the guards of the brackets br.

The tirepot C is also provided inside with a flange, c, to receive thegrate proper D, and outside with a perforated flaugel, to producemore-heating surface for passing atmospheric air to be forewarmed beforeentering the place of combustion.

This ange is also intended to form a protection to the bracket and theguards attached to it, and prevent fuel falling through the grate-barsfrom lodging upon it.

By means of the runner a., the fire-pot and grate-v attached to it maybe turned around the entire circle, every part reached and cleaned.

Flange c is provided with three orinore sockets, to receive and hold inits place cue-half part'of the grate D.

Upon the lower side of 'the outer ring of the grate, conical-formed-projections-.are cast, correspomling with the size of the sockets inwhich theyare to tit.

The grate D, of the usual construction, with plain parallel bars, isdivided into two parts. Ouepart rests on fiange c iu sockets.

o this part the cone E is attached either' permanently, formingone'easting with the bars, or attached to a half circle with slits toreceive the project-ions or -tenons provided for at the base ofcone E,and h'eld in its place.

'lhis half circle is part of .the center. bar ofthe grate, and is alsoconnected with the parallel bars vertical to the center bar.

The cone E is hollow, and perforated with holes to admit air into the.very center of the burning coal.

In stoves with small tire-places the cone may be omitted. -In largetire-places. the number may be increased.'

The other half of the structiomwith parallel bars, and Aarranged 'toopen downward, to remove ashes and ciuders when 4neces-v sary.

lire-grate is of the usualv con.- Y

F is the outer wall 01 shell of the stove. It sits back from thefire-place luxeuough to admit the escape of gases formed and penetratingthrough the holes :md sido wall ofthe fire-pot.'

A C'Zn.

I claim as my inventiou- The combnzxtionof the r-.pot C with thedepend-V ing auge a, anges c and d, grate D, cone E, base A, andbrackets B, substantially as and for the purpose hreinbefore set forth.
